Bringing up the node from SLAT

After the Node is Up and configurations are made, if the node goes for four consecutive crashes, then the node goes to DCN-SLAT mode. When the node goes to DCN-SLAT mode, a new node database with limited configurations would be present in the node, which is only required to provide access to the node. But the previously backed up configurations can be restored. But if the node goes for fifth consecutive crash then the node will come up in default SLAT and needs to be brought up from default SLAT page.

NOTE: If the node goes to DCN-SLAT, the node will be reachable to the user since OSPF related objects information is retained by the node. Provisioning any configuration is disallowed in this mode.

The following page is displayed when the node goes to DCN-SLAT and the alarm 'Configuration missing due to multiple crashes' on object 'SYSTEM-1' will be reported in Active alarms page. Perform Restore configuration if the configuration backup is present. Refer topic Restoring Configuration for restoring the configuration.

The following page is displayed when the node goes to default SLAT mode.

To restore from a previously backed up configuration,

Restore configuration can be performed from SLAT page. In case, the configuration backup is already present, refer to the topic Restoring Configuration for restoring the configuration.

To initialize the node parameters,

1. Click on the Initialize Node Parameters link. The Initialize Node Parameters page is displayed.
2. Enter the node name in the Name field.
3. Enter the functional router ID of the network in the Router ID field.
4. Enter the IP address in the Ethernet IP Address field. The Ethernet IP of each node in the network must be unique.
5. Select the Data Path Mode as SDH or SONET from the drop down option as shown in the figure below.
6. Select the Node Connections Mode from drop-down option.
7. Select the AU Mode as 'AU4' or 'STS1' from the drop down option for desired data path mode selected as 'SDH' or 'SONET' respectively.

   

8. Click Submit. A confirmation page is displayed.
9. Click Accept Valid Modifications. A node reboot warning is displayed.

To Install the software,

1. Click on the Please Install The Software To Proceed link.
2. Select the software download operation option as:
   • Deliver release from local machine
   • Deliver release from remote machine
3. If local machine is selected, provide the file path.
4. If a remote machine is selected, provide the following:
   • User name
   • Password
   • IP of remote machine
   • FTP (optional)
   • Directory
5. Click Submit. The new software gets downloaded to the NE. On completing the download, the system will prompt you to initialize the node parameters like Node Name, Router ID, Ethernet IP, and location.

   On initializing the node parameters, node will go for warm reboot and while the node is coming up, the software gets initialized on the NE. Once the node is up, issue a service disruptive reboot for the FPGAs to get programmed on the NE.

NOTE: After restoring the new database, the node requires a cold reboot for the new configuration to take effect. You can verify the Software Version from the description field of the default WUI page. The Software Version is in the format x.y, where 'x' and 'y' represents major and minor release, respectively.
